If you're doing B2B sales, lead scoring, or account research, you've probably hit the wall where Clearbit wants $99/mo, ZoomInfo wants a sales call, and Dun & Bradstreet wants your firstborn.
But a lot of what these tools provide — company verification, financials, officer names, regulatory status — comes from public government databases. You can query them directly.
Here are the 7 I use most for data enrichment pipelines.
1. Secretary of State Filings (Company Verification)
The most basic enrichment: is this company real? When was it formed? Is it in good standing? Who's the registered agent?
Every state maintains this data. The problem is 50 different portals with 50 different interfaces.
What you can enrich: Legal name, formation date, status, registered agent, principal address, entity type.
I built tools for the largest states: California, Texas, New York, Florida.
2. SEC EDGAR (Public Company Intelligence)
For publicly traded companies, EDGAR is a goldmine. 10-K filings have revenue, risk factors, executive comp, subsidiary lists, and material contracts.
What you can enrich: Revenue, employee count, risk factors, executive names, subsidiary structure, insider ownership.
SEC EDGAR Search — search by ticker, company name, or CIK number.
3. USASpending (Government Contract Revenue)
If your prospect sells to the federal government, this tells you exactly how much, from which agencies, and for what.
What you can enrich: Contract values, awarding agencies, performance dates, NAICS codes, contract descriptions.
USASpending Search — search by company name, DUNS, or agency.
4. FEC Campaign Finance (Executive Political Activity)
Political contribution records include employer names. Search for a company to find which executives donate and to whom. Useful for relationship mapping and PEP screening.
What you can enrich: Executive names, political affiliations, donation amounts, employer verification.
FEC Search — search by individual name, employer, or committee.
5. NPPES NPI Registry (Healthcare Provider Enrichment)
If you sell to healthcare, every provider has an NPI. This database has their specialty, practice address, and organizational affiliations.
What you can enrich: Provider specialty, practice locations, organizational affiliations, enumeration date.
NPPES Search — search by name, NPI, specialty, or state.
6. FDIC BankFind (Financial Institution Data)
Selling to banks? BankFind has total assets, number of branches, holding company structure, and regulatory status for every FDIC-insured institution.
What you can enrich: Total assets, branch count, holding company, regulatory status, FDIC cert number.
FDIC BankFind — search by name, city, state, or cert number.
7. BLS Economic Data (Industry Benchmarking)
The Bureau of Labor Statistics publishes employment, wages, and industry statistics. Useful for benchmarking a prospect's industry or sizing a market.
What you can enrich: Industry employment trends, average wages by occupation, regional economic data.
BLS Data Search — search across multiple BLS data series.
How I Use These Together
For a typical B2B enrichment pipeline:
- Verify the company exists — Secretary of State filing
- Check if they're public — SEC EDGAR for financials
- Check government revenue — USASpending for contract history
- Find decision-makers — FEC records for executive names, NPPES for healthcare
- Assess financial health — FDIC for banks, SEC for public companies
This won't replace a full enrichment platform for every use case. But for verification, compliance, and basic firmographic enrichment, it covers a surprising amount of ground — and it's free.
The main cost is integration time. Each source has different query formats, rate limits, and data structures. That's why I wrapped them into standardized Apify actors that return consistent JSON.
